The search is on for two men who assaulted a female La Salle University student in a park a few blocks from campus.

"These are two violent predators we have to get off the street before they do this to someone else," said Philadelphia Police Commissioner Richard Ross. "You don't do something this horrific and stop there."

Police are investigating a report that the suspects threw bleach on the victim during the attack.

"There is an allegation that some form of bleach-like substance was thrown in her face," Ross told Action News. "They threw her to the ground. She was physically assaulted and possibly sexually assaulted."

Police arrived shortly after the call made by the victim's boyfriend made.

18 yr old La Salle student attacked in Logan. Alert went out overnight to students.
